Mobile IP is a communication protocol which is introduced as an improved version of the IP protocol. With mobile IP the host can move to a different network and still be connected to its home network and can communicate with the remote hosts. In this section, we will discuss mobile IP, it working, several entities of mobile IP, advantages and disadvantages of mobile … [Read more...] about Mobile IP

ICMPv4 Internet Control Message Protocol version 4 is definitely a Network layer protocol and its job is to report the error to the source if any problem arises while delivering the datagram from the source host to the destination host. The ICMPv4 is a message-oriented protocol. It’s a protocol of version of 4 of TCP/IP protocol suite. In this section, we will discuss the … [Read more...] about Internet Control Message Protocol version 4 (ICMPv4)

Address Resolution Protocol (ARP) is a dynamic mapping protocol that maps the IP address of a computer to it's MAC address. ARP maps the 32-bit IPv4 address of the receiver to 48-bit MAC address of the receiver. The Address Resolution Protocol is a Network Layer protocol. There also exists a reverse ARP protocol (RARP) that translates MAC address to IP address. In this … [Read more...] about Address Resolution Protocol (ARP)

Both private and public IP address identifies a specific computer in a network but still, they differ in many ways.  Private IP address is an IP address that identifies a specific computer in a private network. On the contrary, a public IP address identifies a specific computer over the global internet. Private address need not be unique universally but, it has to be unique in … [Read more...] about Difference Between Private and Public IP address

Network Address Translation (NAT) is a method of mapping the private IP address of a private network to the public IP address of the global network and vice versa. With this method, the local host in a private network can access the internet. NAT is used at the routers as they help the router to identify that to which localhost the message is to be forwarded. In this … [Read more...] about Network Address Translation (NAT)

As in classful addressing, some blocks of addresses or some addresses in each block have been reserved for the special purpose & that’s why they are termed as special IP addresses. The special addresses of classful addressing were inherited by the classless addressing when it was introduced in 1996. There can be an entire block of addresses reserved for special … [Read more...] about Special IP Addresses in IPv4

Classless addressing is a concept of addressing the IPv4 addresses. It was adopted after the failure of classful addressing. The classful addressing leads to wastage of addresses as it assigns a fixed-size block of addresses to the customer. But, the classless addressing assigns a block of addresses to the customer according to its requirement which prevents the wastage of … [Read more...] about Classless Addressing in IPv4

Classful addressing is a concept that divides the available address space of IPv4 into five classes namely A, B, C, D & E. Nowadays, this concept has become obsolete and has been replaced with classless addressing. IP addresses, before 1993 use the classful addressing where classes have a fixed number of blocks and each block has a fixed number of hosts. In this section, we … [Read more...] about Classful Addressing in IPv4

Connection oriented and Connectionless services are the two data transmission services provided by the network layer protocols and transport layer protocols. The Connection oriented services establish a connection prior to sending the packets belonging to the same message from source to the destination. On the other hand, the connectionless service considers each packet … [Read more...] about Connection Oriented and Connectionless Services
